        FF FF 

So this means:

"/" contains folder "data" which has contents [01 F0]
"data" contains folder "stage" which has contents [02 F0]
"stage" contains folder "vs_cross" which has contents [03 F0]
"vs_cross" holds five files, as listed


Directories:
[0x80 | namelength] [name string] [ID of directory contents]

Files:
[0x7F & namelength] [name string]

Directories and files listed sequentially. When done, terminate with a null.
The whole thing ends with [FF FF].
